INLINE TRANSDUCER HOUSING ASSEMBLY
An inline transducer meter body can be fabricated by 3D moulding via use of a liquid cooled moving core and include a channel that can accept a separate core to enable formation of a port to accept a sensor assembly and a notch to help stabilize the sensor assembly in alignment with fluid flow. The inline transducer meter body can include a circular shelf adapted to receive a transducer assembly that interfaces in a complimentary manner with a circular ledge of a circular head section of the transducer assembly, a portal formed between the circular shelf and an inner surface of the housing adapted to interface in a complimentary manner with an alignment section of the transducer, and a notch formed in the inner surface of the flow tube opposite the portal to interface with a positioner formed on and extending from a transducer holder operating to secure the transducer holder flow alignment.
Embodiments are related to fluid flow meters, More particularly, embodiments are related to a flow meter adapted to securely place and hold an inline transducer housing assembly within fluid flowing through a conduit. Embodiments are &so related to use of an injection mould tool utilizing 3D printed inserts to render an inline transducer housing assembly body.
BACKGROUNDFlow meters are sophisticated measuring devices that employ a range of technologies designed to quantify the rate or volume of a moving fluid, either liquid or gas, in an open or closed conduit. The type of flow meter used will vary by application, but coriolis, differential pressure, magmeter, electromagnetic, oval gear, thermal, paddlewheel, positive displacement and ultrasonic are the most commonly used technologies.
Ultrasonic flow meters use sound waves as a reliable, accurate and maintenance free method to measure the velocity of a fluid from which the volumetric flow rate can be calculated. They feature no moving parts making them more reliable and accurate while providing maintenance-free operation, Since ultrasonic signals can also penetrate solid materials, the transducers can be mounted onto the outside of the pipe offering completely non-invasive measurement eliminating chemical compatibility issues, pressure restrictions, and pressure loss. Inline mounting of transducers, however, can provide the most accurate measurement of fluid flow.
Despite improvements in technology, it can still be a challenge to achieve accurate fluid flow measurement over a long period of time without degradation of quality or sensor integrity given challenges that can be experienced when transducers are placed within (i.e., in-line with) the flow of fluid to be measured. What is needed are improvements in the placement of transducers within a conduit wherein fluid is flowing through the conduit.
SUMMARYEmbodiments are presented to achieve accurate inline fluid flow measurement over a long period while minimizing degradation of measurement data quality.
The following summary is provided to facilitate an understanding of some of the features of the disclosed embodiments and is not intended to be a full description. A full appreciation of the various aspects of the embodiments disclosed herein can be gained by taking the specification, claims, drawings, and abstract as a whole.
Embodiments presented are also to achieve accurate inline fluid flow measurement over a long period while minimizing degradation of quality by using ultrasonic flow-rate sensing technology.
